<p>PURPOSE:To make a flow rate to be outputted to an output chamber securable so ample enough, by installing a control valve, being controlled according to suction pressure, and a subvalve, being opened after opening the side valve, both in a control valve which regulates output pressure by means of the discharge pressure and the suction pressure of a compressor. CONSTITUTION:In case of a compressor in which a reciprocating stroke of a piston is made variable according to a rocking angle of a rocking plate to be rotated by an engine and its discharge is controlled, there is provided with a control valve 123 which regulates output pressure by discharge pressure and suction pressure of the compressor and outputs it to a control pressure chamber. This valve 123 opens a control valve 205, via a piston 208, by the lowering of a diaphragm 213 to be displaced according to differential pressure between a suction pressure chamber, where the suction pressure is introduced from a hole 201, and a constant pressure chamber 210, while it opens a subvalve 214 by the successive lowering of the piston 208, thus it is constituted so as to make control pressure inside a discharge pressure chamber 228, to be outputted to an output chamber 225, raisable.</p> |
